Contact Voltage Detection with Power Survey from Osmose

Contact Voltage: Unseen and Unforgiving
215,000 energized structure found in 75 cities

Electric grids are complex systems, where key components are interdependent and inevitably subject to degradation over time. While above-ground grid assets can be inspected visually and repaired as needed, below-ground infrastructure remains unseen and major hazards can go undetected. And it is from here – out of sight - that contact voltage poses a costly and unforgiving danger.

Awareness of this hidden risk is not the problem: detection is. Pro-active detection is the only responsible course of action. Contact voltage cannot be reliably detected with manual or visual inspection, like a rotting wooden pole or a corroding steel transmission tower. The solution is Power Survey from Osmose – which relies on advanced technology in its MAAV or Mobile Asset Assessment Vehicles, which identifies problem areas that can be addressed before they impact safety or lead to electrical losses. The MAAV has a sophisticated electric field detection system focused on detecting high impedance faults in underground distribution systems – typically in urban and city settings.

Advanced Technology Detects Hidden Hazards

Public objects like streetlights, traffic signals, playground equipment and fences—even concrete—can become energized and dangerous. Osmose’s Power Survey helps utilities manage this risk by scanning all essential underground assets and identifying problem areas, which can then be eliminated.

Power Survey was the first (and remains the only) mobile scanning system designed to detect contact voltage faults. Mobile electric field detection is the most sensitive and accurate non-invasive testing method available to locate faults in underground distribution systems. Osmose’s Power Survey system is an industry benchmark that remains unequaled in sensitivity and performance.
